class_docstr: The FB15K237 dataset from the `"Translating Embeddings for Modeling
  Multi-Relational Data"
  <https://papers.nips.cc/paper/5071-translating-embeddings-for-modeling
  -multi-relational-data>`_ paper,
  containing 14,541 entities, 237 relations and 310,116 fact triples.
  
  .. note::
  
      The original :class:`FB15k` dataset suffers from major test leakage
      through inverse relations, where a large number of test triples could
      be obtained by inverting triples in the training set.
      In order to create a dataset without this characteristic, the
      :class:`~torch_geometric.datasets.FB15k_237` describes a subset of
      :class:`FB15k` where inverse relations are removed.
  
  Args:
      root (str): Root directory where the dataset should be saved.
      split (str, optional): If :obj:`"train"`, loads the training dataset.
          If :obj:`"val"`, loads the validation dataset.
          If :obj:`"test"`, loads the test dataset. (default: :obj:`"train"`)
      transform (callable, optional): A function/transform that takes in an
          :obj:`torch_geometric.data.Data` object and returns a transformed
          version. The data object will be transformed before every access.
          (default: :obj:`None`)
      pre_transform (callable, optional): A function/transform that takes in
          an :obj:`torch_geometric.data.Data` object and returns a
          transformed version. The data object will be transformed before
          being saved to disk. (default: :obj:`None`)
      force_reload (bool, optional): Whether to re-process the dataset.
          (default: :obj:`False`)
